During the last decade of the 1990s, the search engine landscape was very competitive. You had a choice of search engines (human-powered directories, and directories based on crawlers), including AltaVista, Ask Jeeves, Excite, Infoseek, Lycos, and Yahoo.
Search Engine Optimization Story, 20 years of SEO
If you wanted to rank well at that time, the trick was to repeat your keywords enough times in your web pages and meta tags. Do you want to top a page that uses a keyword 100 times? Then you would use the keyword 200 times! Today we call this practice spamming.
Although it can be said that SEO and all search engine marketing began with the launch of the first published website in 1991, or perhaps when the first web search engine was launched, the history of SEO begins “officially” a little later, around 1997.
Let’s go back in time, more precisely to 1998, when Google was born as a result of the work of two computer scientists, Sergey Brin and Larry Page. For the record, the name of the brand comes from the word googl, a mathematical term that is worth 10 powers of 100. Just that !!.
The ranking of the results on the search engine was, at first, 100% natural. It was simple, it based its results only on the correspondence between keywords and sites. That’s when the marketers of the time realized that by modifying a few elements of their sites, they were climbing in the ranking. These were the beginnings of search engine optimization and thus the birth of SEO.
The Google revolution
Previously, Google was a little-known search engine. Barely known! The end result: every Yahoo search result said “Powered by Google” and they ended up introducing their biggest competitor in the world and Google became a household name.
But the web crawler, and Google’s PageRank ranking algorithm, were revolutionary for information retrieval. Google looked at both on-page and off-page factors, i.e. the quantity and quality of external links pointing to a website (as well as the anchor text used).
If you think about it, Google’s algorithm was essentially to say “if people are talking about you, you must be important”.
Google AdSense: monetize a website
Although Google probably didn’t realize it at the time, they were creating problems that they would have to fix later.
AdSense led to spam tactics and sites specifically designed for AdSense that contained low-volume, poor or stolen content and existed only to rank well, get clicks, and make money.
Local referencing and customization
It was also around 2004 that Google and search engines began to make greater use of end-user data, such as search history and interests, to customize search results.
This meant that the results you saw might be different from those of another person sitting next to you in a coffee shop when searching for the same query.
Also in 2005, nofollow tags were created to combat spam. SEO professionals began using this tag as a way to sculpt PageRank.
YouTube, Google Analytics and tools for webmasters
Today, YouTube has more than one billion users. Due to its growing popularity, video SEO has become crucial for brands, companies, and individuals who want to be found.
Google also launched two extremely important products in 2006
Google tools for webmasters.
Now known as the Search Console, Google’s webmaster tools allow webmasters to view analysis errors, search for searches on your site, and request re-inclusions.
Also in 2006, XML sitemaps were universally recognized by search engines. XML sitemaps allow webmasters to display on search engines each URL of their website available for analysis.
An XML sitemap contains not only a list of URLs but also a range of additional information, which has enabled search engines to explore more intelligently.
The meteoric rise of social networks
Google made its big bet on YouTube, but other networks such as Facebook, Twitter, and LinkedIn, have all emerged as major players (many more will come and go in the coming years).
In parallel with the rise of social networks, speculation that social signals can affect search rankings has emerged.
While the impact of social shares (likes, tweets, +1, etc.) has been repeatedly rejected by Google over the years as a ranking factor, it has continued to be listed as highly correlated in various ranking factor studies.
Starting about 2005, a question was asked in our area. Is it the year of the mobile?
Then from the years 2011, 2012, 2013, and 2014, Mobile got a lot of attention and excitement because it was growing like a snowball effect all the time.
As users adopt smartphones, they were increasingly looking for companies and products on the go.
Finally, in 2015, we had the Year of the Mobile Phone – the moment when mobile search overtook computers to search for the first time on Google.
It was also in 2015 that Google launched a much-anticipated update of its mobile-enabled algorithm, designed to give users “the most relevant and timely results, whether the information is on mobile-friendly web pages or in a mobile application.
AI, and intelligent research
Today, Google search is designed to inform and help rather than give users a list of links. This is why Google has integrated artificial intelligence in all its products: search, Gmail, AdWords, Google Wizard, etc.
Voice searches are on the rise, but also visual search has become incredibly good. And users (and brands) are increasingly adopting chatbots and using PDAs (for example, Apple’s Siri, Amazon’s Alexa, and Microsoft’s Cortana).
The history of SEO has been rich in twists and turns: the birth of new search engines, the disappearance of old search engines, new SERP features, new algorithms, and constant updates, not to mention the emergence of quality SEO publications, conferences, tools, and experts.
